This document provides details about designing a computer mouse for a class project. It begins by defining the problem of non-responsive buttons or scroll wheels that can often be fixed by cleaning debris. It then gathers pertinent information about what a computer mouse is and its common components. Next, it generates multiple solution options, such as types of mice based on connectivity, buttons for specific tasks, and motion tracking technologies. It analyzes these solutions and selects a projection computer mouse that projects a mouse layout and records movements to send to a computer.

2. COMPUTER MOUSE
DEFINE THE PROBLEM
If the mouse scroll wheel is non-responsive or the click
buttons are not working open the mouse casing and clean
the buttons or scroll wheel hub and remove the debris using
a pointed object like toothpick, etc. If the mouse wheel is
not free to rotate or there is some friction, then put WD-40
spray.

3. Gather Pertinent Information
❏ A computer mouse is a hand-held pointing device that detects
two-dimensional motion relative to a surface.
❏ This motion is typically translated into the motion of a pointer
on a display, which allows a smooth control of the graphical
user interface of a computer.
❏ In addition to moving a cursor, computer mice have one or
more buttons to allow operations such as the selection of a
menu item on a display. Mice often also feature other
elements, such as touch surfaces and scroll wheels, which
enable additional control and dimensional input.

4. Generate Multiple Solution
❏ There are different types of computer-mouse, and are based on connectivity to
the computer or medium for signal transfer, utility or number of buttons or
functions required for specific tasks. e.g Gamers require computer mouse
having most of the functions localized in the hand-held mouse using different
buttons that are more accessible in the real time, and also on the basis of motion
tracking technology.
❏ Nowadays, computer mouse use different technology for connectivity or signal
transfer to the computer using wireless systems like bluetooth, or usb nano
receivers. These mouse provide function control, even from a greater distance.
❏ Earlier, mouse used ball for motion tracking. These days, laser-imaging and
invisible-optics are used.

5. Analysis and Select a Solution
❏ A projection computer mouse is an advanced computer
peripheral and a pointing device, where a laser projector
projects a layout of a mouse, it’s keys, and the scrolling
wheel on a plane surface and it records the keystrokes or
finger movements on the surface and sends the signal to
the computer.
❏ The projector unit is connected to the computer via a usb
cable, a usb nano-receiver or using bluetooth.
